Description

SUBSONIC 6.5 Creedmoor- New Sig brass, Prvi 156 grain RN @ 1050 fps in 22″ barrel. Priced per 100 rounds. This bullet requires a 1:8″ twist to fully stabilize. A 1:8.5″ twist will give oblong, egg shaped holes on your target at 100 yards, but still shoots decent.

 

Priced per 100 rounds.

Why use a 156 or 160 grain RN (round nose or soft point) flat base bullet, instead of a BTHP or match bullet? When shooting at subsonic speeds, bullet stability becomes a huge factor for the bullet to properly stabilize and for it to shoot well. Bullet length is a major factor in how stable it is out of the muzzle. In a given twist rate (like a 1:8″ barrel twist) and slow subsonic speeds, a shorter, flat base bullet is more stable than a longer BTHP match bullet is of the same weight. The 160 grain RN flat base is a much shorter bullet than a similar weight BTHP bullet, like a 140 grain Berger or similar BTHP bullet. This allows the 160 grain RN flat base to be more stable and have the potential to be more accurate at subsonic speeds than a BTHP design. BC (ballistic coefficient) is for supersonic flight, and does not matter at subsonic speeds. Having a high BC bullet at subsonic speeds does not benefit the shooter at all. This is why the 160 RN flat base bullets work well as a subsonic round!
